Why do I say (repeatedly, year after year) that the best goal for the climate talks is to make progress on a sound foundation for meaningful, long-term global action, not some notion of immediate triumph? The reason is that the often-stated cliche about the American baseball season — that it’s a marathon, not a sprint — applies even more so to international climate change policy. Why?

First, the focus of scientists (and policy makers) should be on stabilizing concentrations at acceptable levels by 2050 and beyond, because it is the accumulated stock of greenhouse gas emissions — not the flow of emissions in any year — that are linked with climate consequences.

Second, the cost-effective path for stabilizing concentrations involves a gradual ramp-up in target severity, to avoid rendering large parts of the capital stock prematurely obsolete.

Third, massive technological change is the key to the needed transition from reliance on carbon-intensive fossil fuels to more climate-friendly energy sources. Long-term price signals (most likely from government policies) will be needed to inspire such technological change.

Fourth and finally, the creation of long-lasting international institutions is central to addressing this global challenge.

For all of these reasons, international climate negotiations will be an ongoing process, not a single task with a clear end-point. Indeed, we should not be surprised that they proceed much as international trade talks do, that is, with progress only over the long term, building institutions (the GATT, the WTO), yet moving forward in fits and starts, at times seeming to move backward, but with progress in the long term.

So, the bottom-line is that a sensible goal for the international negotiations in Durban is progress on a sound foundation for meaningful long-term action, not some notion of immediate “success.” This does not mean that there should be anything other than a sense of urgency associated with the work at hand, because it is important. But it does mean that we should keep our eyes on the prize.

How Can the Durban Negotiators Keep their Eyes on the Prize?

The keys to success — real, as opposed to symbolic success — in Durban depend upon four imperatives.

1. Embrace Parallel Processes

The UNFCCC process must embrace the parallel processes that are carrying out multilateral discussions (and in some cases, negotiations) on climate change policy: the Major Economies Forum or MEF (a multilateral venue for discussions – but not negotiations – outside of the UNFCCC, initiated under a different name by the George W. Bush administration in the United States, and continued under a new name by the Obama administration, for the purpose of bringing together the most important emitting countries for candid and constructive discussion and debate); the G20 (periodic meetings of the finance ministers – and sometimes heads of government – of the twenty largest economies in the world); and various other multilateral and bilateral organizations and discussions.

The previous leadership of the UNFCCC seemed to view the MEF, the G20, and most other non-UNFCCC forums as competition – indeed, as a threat. Fortunately, the UNFCCC’s new leadership under Executive Secretary Christiana Figueres (appointed by UN Secretary-General Ban Ki-moon in May of 2010) has displayed a considerably more positive and pragmatic attitude toward these parallel processes. That’s a positive sign.

2. Consolidate Negotiation Tracks

There are now three major, parallel processes operative: first, the UNFCCC’s KP track (negotiating national targets for a possible second commitment period – post-2012 – for the Kyoto Protocol); second, the LCA track (the UNFCCC’s negotiation track for Long-term Cooperative Action, that is, a future international agreement of undefined nature); and third, the Cancun Agreements from COP-16 a year ago (based upon the Copenhagen Accord, negotiated and noted at COP-15 in Copenhagen, Denmark, in December, 2009). Consolidating these three tracks into two tracks (or better yet, one track) would be another significant step forward.

The primary way for this to happen would be for the LCA negotiations to focus on the ongoing work of putting more meat on the bones of the Cancun Agreements, which — along with the Copenhagen Accord — marked an important step forward by blurring for the first time (although not eliminating) the unproductive and utterly obsolete distinction in the Kyoto Protocol between Annex I and non-Annex I countries. (Note that more than 50 non-Annex I countries have greater per capita income than the poorest of the Annex I countries.)

In particular, the UNFCCC principle of “common but differentiated responsibilities” could be made meaningful through the dual principles that: all countries recognize their historic emissions (read, the industrialized world); and all countries are responsible for their future emissions (think of the rapidly-growing, large, emerging economies of China, India, Brazil, Korea, Mexico, and South Africa).

As I’ve said before, this would represent a great leap beyond what has become the “QWERTY keyboard” (that is, unproductive path dependence) of international climate policy: the distinction in the Kyoto Protocol between the small set of Annex I countries with quantitative targets, and the majority of countries in the world with no responsibilities. A variety of policy architectures — including but not limited to the Cancun Agreements — could build on these dual principles and make them operational, beginning to bridge the massive political divide that exists between the industrialized and the developing world.

A third area of success at the Durban negotiations could be realized by some productive steps with specific, narrow agreements, such as on REDD+ (Reduced Deforestation and Forest Degradation, plus enhancement of forest carbon stocks). Other areas where talks are moving forward, although somewhat more slowly, are finance and technology, particularly in the context of adding meat to the bones of the Cancun Agreements.

4. Maintain Sensible Expectations

Finally, it is important to go into these annual negotiations with sensible expectations and thereby effective plans. As I said at the outset, negotiations in this domain are an ongoing process, not a single task with a clear end-point. The most sensible goal for Durban is progress on a sound foundation for meaningful long-term action, not some notion of immediate triumph. The key question is not what Durban accomplishes in the short-term, but whether it helps put the world in a better position five, ten, and twenty years from now in regard to an effective long-term path of action to address the threat of global climate change.

Wait, What About the Kyoto Protocol?

Those who follow these international negotiations closely — including my colleagues on the ground in Durban — are no doubt wondering why I haven’t said something about the 900-pound gorilla in the closet: the fact that the Kyoto Protocol’s first (and so far only) commitment period runs from 2008 through 2012, and so a decision needs to be reached on a possible second (post-2012) commitment period for the Protocol.

Yes, in addition to the LCA (Cancun) track, the Kyoto Protocol (KP) track of negotiations remains. A decision regarding a possible extension (and presumably an enhancement) of the Kyoto Protocol’s emission-reduction targets for the industrialized (Annex I) countries has been punted annually to the next set of negotiations — from Bali in 2007, to Poznan in 2008, to Copenhagen in 2009, to Cancun in 2010, and now to Durban in 2011. It can’t be delayed any longer, because the necessary process of ratification by individual nations would itself take at least a year to complete.

Keeping the Kyoto Protocol going (and with more stringent targets for the Annex I countries) is very important to the non-Annex I countries, sometimes referred to — inaccurately — as the developing countries. I don’t blame them. An approach that provides benefits (reduced climate damages, as well as financial transfers) for the non-Annex I countries without their incurring any costs is surely an attractive route for those nations.

Is a Second Commitment Period for the Kyoto Protocol Feasible?

Putting aside the possible merits of a second commitment period for the Kyoto Protocol, we can ask simply whether it’s in the cards: is it feasible?

Japan, Russia, and Canada have formally announced that they will not take up targets in a second commitment period. Australia, despite its recent domestic climate policy action, seems unlikely to make a significant commitment. Is Europe (plus New Zealand) on its own credible or feasible? Maybe yes, maybe no.

The “yes” part of the answer comes from the fact that Europe has already committed itself to serious emissions reductions through the year 2020 under the European Union Emission Trading Scheme (EU ETS). This will go forward — barring a change of heart by the EU — with or without a second commitment period for the Kyoto Protocol. That said, Europe’s compliance costs under the EU ETS will be much less than otherwise if offsets continue to be made available from non-Annex I countries under the Kyoto Protocol’s Clean Development Mechanism (CDM). This might suggest that the EU has a significant motivation to keep the Kyoto Protocol going.

This highly contentious issue of a possible second commitment period for the Kyoto Protocol may come to dominate the talks in Durban. This would be unfortunate, because it would simultaneously reduce the likelihood of the negotiators making progress on a sound foundation for meaningful, long-term global action. It would probably also have the effect of producing some drama in the form of highly-charged debates, and possible threats by some delegations to walk out of the negotiations. For this reason, despite the weather, Durban may come to resemble Copenhagen more than Cancun.

The Harvard Project on Climate Agreements has pulled together an archive of relevant publications, which we call “The Durban Branch” of our climate library. We hope it will be helpful for those gathered in Durban or watching from afar.

Also, a number of previous essays I have written and posted at this blog will be of interest to those who wish to follow developments at the Seventeenth Conference of the Parties of the UN Framework Convention on Climate Change in Durban. Here are links, in reverse chronological order:
